Richardson (hamstring) has no injury designation ahead of Sunday's matchup against the Steelers, Paul Gutierrez of ESPN.com reports.
Richardson missed the Raiders' first five games this season due to a hamstring injury sustained at the beginning of September. However, the rookie out of Mississippi State upgraded from limited work Thursday to a full practice Friday, suggesting he's moved past his hamstring issue. He's expected to serve as a depth piece in the Raiders' secondary in his NFL debut.
